Marylebone Knurled Lever Lock Door Handle on Backplate - Matte Black - Pair - Designer Levers

You must install a mortice lock with a door handle to operate with a key for added security to your room.

Door Handle Style:

• For lever door handles, we recommend using a 64mm mortice lock.
• We recommend using a 76mm mortice lock for doorknobs to allow for more room to manoeuvre the doorknob.

Security Level:

• We recommend using a 2 or 3-lever mortice lock for rooms that require a low level of security.
• For rooms that require a greater level of security, we recommend a 5-lever mortice lock - particularly if this is an external door.

Butt hinges are the most prevalent type of hinges used when hanging doors. However, the number of hinges needed per door can vary; this is dependent on the size and construction of the door.

We recommend 76mm (3”) hinges for lightweight interior doors and 100mm (4”) hinges for solid/ heavy-duty interior doors.

If you have a solid wooden door, we recommend using at least three hinges per door, and any door taller than 2200mm should be fitted with four.
